In context
17So they turned to the blind man again: “What do you say about him? It was your eyes he opened.” He said, “He is a prophet.” 18The Jews still refused to believe that he had been blind and received his sight, until they summoned the parents of the man who now saw 19and asked them, “Is this your son, the one you say was born blind? Then how is it that he now sees?” 20His parents answered, “We know that this is our son, and that he was born blind. 21But how it is that he now sees, we don’t know; nor do we know who opened his eyes. Ask him — he is of age; he will speak for himself.”
